Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability json-to-csv-converter-3469bc88 -d '<json body>'
```

Example prompt: Take this JSON array of user records and convert it to a CSV with a header row so I can open it in Excel: [{"name":"Alice","age":30,"city":"NYC"},{"name":"Bob","age":25,"city":"LA"}].

## When to prefer this

Choose this endpoint when you have a flat or shallow JSON array of objects and need a quick, cheap CSV conversion without standing up any local processing. Ideal for agents preparing data exports for spreadsheets, reporting tools, or bulk upload interfaces. If your JSON is deeply nested and you need recursive flattening, a more specialized transformation service may be needed.

## Known failure modes

- Input is not a valid JSON array — returns a parse error
- Input is an array of primitives rather than objects — header row cannot be derived
- Inconsistent keys across objects — missing fields may appear as empty columns
- Empty array input — may return only a header row or an error
- Deeply nested objects — nested values may be serialized as strings rather than flattened

## How this service works

Flatten a JSON array of objects into CSV with a header row.

## Output

A plain-text CSV string with a header row derived from the keys of the first JSON object, followed by one data row per element in the input array, with values comma-separated and properly escaped.
